摘　　要：为了明确背腺毛腺孔位置形态是否可作为急流水螨分类性状使用,本研究运用几何形态测量学的方法对急流水螨7属59种129个样本的背腺毛腺孔位置形态进行了变异分析。通过主成分分析明确了急流水螨7属间背腺毛腺孔位置形态的变异趋势,即急流水螨背腺毛腺孔形态的变异主要集中于D_(2)(由靠近螨体外侧向螨体中部移动)、D_(1)(靠近或远离螨体边缘)、D_(4)(由螨体后部向螨体中部前移)的变化;通过典型变量分析、聚类分析明确了急流水螨7属间背腺毛腺孔位置形态差异显著。该研究结果表明,背腺毛腺孔位置形态特征可作为急流水螨属级阶元的分类性状,同时初步表明几何形态测量学可用于急流水螨分类研究。In this study,the geometric morphometry method was used to digitize the position and morphological of glandular pores of dorsalglandularia in 129 samples of 7 genera,59 species of torrenticolid water mites to determine whether the position and morphological of glandular pores of dorsalglandularia used as their taxonomic characteristics.The variation trend of position and morphology of glandular pores of dorsalglandularia among 7 genera were determined by principal component analysis.The morphological variation of glandular pores of dorsalglandularia of torrenticolid water mites was mainly concentrated in D_(2)(moving from the outside of mite to the middle of mite),D_(1)(close to or away from the edge of mite),and D_(4)(moving from the back of mite to the middle of mite).There were significant differences in the position and morphological of dorsalglandularia by canonical variable analysis and cluster analysis.The results showed that the position and morphological characteristics of glandular pores of dorsalglandularia could be used as taxonomic characters in 7 genera of Torrenticolidae.This finding provides that the geometric morphometry could be utilized in the classification of torrenticolid water mites.
